also....i was on Metformin for the pcos for 2 years...and during all my IUIs i was on it(1500mg/day) BUT my new RE has taken me off of it. im not sure how well it worked for me. it may have helped regulate my insulin...but i doubt it helped me ovulate. i tend to ovulate late in my cycle..and i have cycles that vary from 27 days to 24 days in length.
i was on medication(fertility medication like Clomid and Puregon) during all of my IUIs to help me grow eggs, and to help me grow them in time with my hormones to properly ovulate at the correct time(or close to it!)
